DMA22734
Pinouts
The ERG DMA22734 (DMA SeriesDMA Series
DMA SeriesDMA Series
DMA Series) DC
to AC inverter features onboard connectors
and can be easily dimmed using an external
pulse-width modulated control signal. This
unit is less than 13mm in height and the two
mounting holes make installation very straight
forward.
Powered by a regulated +5 volt DC source the
DMA22734 is specially designed to power the
Sharp LQ104S1DG21 backlight.

Specifications subject to change without notice.
(Note 1) Surface temperature must not exceed 80 degrees C; thermal management actions may be required.
(Note 2) Input current in excess of maximum may indicate a load/inverter mismatch condition, which can result
in reduced reliability. Please contact ERG technical support.
(Note 3) Provided data is not tested but guaranteed by design.
Application Notes:
1) The minimum distance from high voltage areas of the inverter to any conductive material should be .12
inches per kilovolt of starting voltage.
2) Mounting hardware to be non-conductive.
3) Open framed inverters should not be used in applications at altitudes over 10,000 feet.
4) ACreturn should be left floating, not grounded.
5) Contact ERG for possible exceptions.

Note 1 Low ESR type input by-pass capacitor (22 uF - 100 uF) may be required to reduce reflected ripple.
Note 2 VPWM from 2.4V to less than or equal to +Vin.
Note 3 Full brightness without PWM control requires that pin 5 be tied to +Vin, Pin 5 must be at 0V to turn off.
